As technology advanced, more and more automobile makers began to combine physical and electronic protocols in order to prevent theft. These key systems are called transponder keys or chip keys, and they're designed to make it more difficult for thieves to get into the vehicle.
The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver in your car.

This energy is absorbed by the chip and sends back the radio frequency signal, which includes an identification code that is matched with the unique serial number in the car's computer system. This is to prevent unauthorised attempts to start the car since only right keys can be used.
